Patent DE-3323781-A1 (DE)
Inventor: MEVENKAMP PAUL DIPL ING
IPC: F28F9/02
Filed: 1983-07-01
Abstract: A device is provided for direct cooling of thick essentially horizontal wall members which are charged with different temperatures and possibly different pressures on their upper and lower sides, such as for cooling a heat exchanger tube sheet. Cooling of the wall member or component from the "cold side" is afford by closed end bores formed in the wall member which bores are open on the "cold side" and closed on the "hot side". Each closed end bore has a tube projecting from the "cold side" of the wall member and extending into the bore with its end within the bore located adjacent the closed end of the bore. The diameter of the tube is smaller than the diameter of the bore so that flow through the tube into the bore can reverse direction at the closed end and flow through the space between the tube and the bore.

Title: Device for dissipating the heat losses of electrical assemblies
Inventor: WAIDHAS WUNIBALD DIPL ING
IPC: H05K7/20
Filed: 1983-07-18
Abstract: A device for dissipating the heat losses of electrical assemblies. The heat-generating components (6) of an electrical assembly are arranged on a large-area support (25), which is supported such that it can move relative to a housing outer wall (21) and which, during the attachment of the assembly front panel (8), is pressed against a contact part (26) which is mounted on the inner surface of the outer wall (21), or against the outer wall (21) itself. In consequence, a heat-conducting connection is produced between the components and the housing outer wall, which can be cooled. The invention is suitable for heat dissipation from assemblies, for example for power supplies. <IMAGE>

Patent DE-3330116-A1 (DE)
Title: X-ray diagnostic generator
Inventor: MAGERSTAEDT HANS-JUERGEN DIPL
IPC: H05G1/46
Filed: 1983-08-20
Abstract: The invention relates to an X-ray diagnostic generator having means, which are arranged on a control surface, for setting recorded data programmed on the basis of organs. The invention is intended to achieve an ergonomically simple control capability, it being intended on the one hand that the organ selection should not require detailed attention, while on the other hand the number of necessary control operations on such an X-ray diagnostic generator should remain as low as possible. The essential feature of the invention is that the control surface is divided into a first region having a plurality of display areas in which in each case organs of a specific anatomic region are displayed, and in each case different colours, which are repeated in each display area, are allocated to these representations, and push-button switches which are allocated to the display areas are used for selecting the anatomical region, and into a second region having a keyboard in matrix form, whose push-button switches are used on the one hand for organ selection and on the other hand at the same time for selecting a further parameter, such as the recording direction, the push-button switches being characterised, in columns or rows, in each case by means of one of the colours which is correspondingly allocated to the organs in the display areas and, as an alternative to this, the further parameter, for example in each case one of the recording directions, being allocated to each row or column. <IMAGE>
Patent DE-3331516-A1 (DE)
Title: Backacter loader
Inventor: PINGON PIERRE JOSEPH DE
IPC: E02F3/30
Filed: 1983-09-01
Abstract: Backacter loader with a boom which is subdivided into an initial boom (9) and a main boom (18), the main boom being linked to the free end (17) of the initial boom (9). The initial boom is pivotably mounted on the front end of the slewing ring (3) of the machine and can assume a position inclined to the rear, in which its free end is clearly located behind the axis of rotation of the slewing ring and above the slewing ring. In this position, the main boom can be folded back onto the initial boom and extend essentially horizontally to the front, its front end being located roughly above the front part of the machine. In this position, the arm (24) carrying the tool can in principle be directed vertically downwards. This facilitates the loading work. For the excavating work, the boom is unfolded roughly until extension of the initial boom and is locked relative to the latter.

Patent DE-3422594-A1 (DE)
Title: Process for the preparation of a non-toxic, stomach-compatible newspaper printing ink
Inventor: ZIEGLER WALTER
IPC: C09D11/02
Filed: 1984-06-18
Abstract: The known newspaper printing inks have foul-smelling solvents for lacquers. In damp weather, they adhere to the hands. When the dye is washed out of the newspaper to reuse the paper, environmentally harmful effluent results in the sewer. The dye of the process according to the invention does not have these disadvantages. This dye is based on ethyl alcohol, which can be recovered without residue in the printing process or on washing out. The dye can be washed out of the newspaper very rapidly and easily using undenatured ethyl alcohol. The black dye is animal charcoal/activated charcoal and has a double function, because at the end it bleaches the residual shellac away completely. No grey haze and no dusting of the paper in the printing works results. The dye consists of a mixture of animal shellac, dewaxed, of high melting point, vegetable resin, hardened, of high melting point, beeswax of high melting point, olein from tallow ethyl alcohol, non-toxic and denatured, black animal charcoal/activated charcoal - very finely pulverised, which parts are mixed intimately with one another. By addition of food dyes, for example red or yellow, a wish for any desired colour can be met.

Patent DE-3437151-A1 (DE)
Title: Heat engine
Inventor: FEIST ARTUS
IPC: F02G5/02
Filed: 1984-10-10
Abstract: The heat engine is a modified four-stroke internal combustion engine. This is designed not for maximum torque but for maximum heating. To this end an expansion chamber is connected to the exhaust valve. On the expansion stroke the exhaust valve opens after the top dead centre and remains open until completion of the exhaust stroke. Between the exhaust valve and the expansion chamber is a further line with up to approximately twenty times the volume of a cylinder of the internal combustion engine. The line and the expansion chamber are located in a heat exchanger. A temperature sensor measures the temperature at the outlet of the expansion chamber and at the outlet end of the heat exchanger. The inlet and the exhaust valve of the cylinder are controlled according to the temperature difference. The combustion gases expand in the line. As a result the expansion chamber is less stressed. Control of the valves thermally relieves the expansion chamber.
